Science Buddies: "Ask an Expert"

what mosfet and diode did you use on your Motion-Activated Guard Robot (BlueBot Project #1) please help me its for my project in school

Hi, here are the parts we use, but Jameco has a $20 minimum order otherwise they charge you extra for shipping:

This MOSFET from SparkFun should be functionally equivalent and they should have cheaper shipping, but the diode is currently on backorder:

You could also check to see if these parts are available on Amazon.

thanks
